It's already possible to do what you want. Have the learned flows set a register to a distinctive value, such as 1, and match on that register after resubmitting to the table that contains the learned flows. In the next table, if the register contains the value, resubmit to table 22, otherwise don't. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
